Response Syntax


HTTP/1.1 201
Content-type: application/json

{
   "InitialConfigurationToken": "string"
}

Response Elements

If the action is successful, the service sends back an HTTP 201 response.

The following data is returned in JSON format by the service.

InitialConfigurationToken

Token encapsulating state about the configuration session. Provide this token to the GetLatestConfiguration API to retrieve configuration data.

Important

This token should only be used once in your first call to GetLatestConfiguration. You must use the new token in the GetLatestConfiguration response (NextPollConfigurationToken) in each subsequent call to GetLatestConfiguration. If there is no change to a configuration, the token doesn't return the AWS AppConfig configuration profile.

The InitialConfigurationToken and NextPollConfigurationToken should only be used once. To support long poll use cases, the tokens are valid for up to 24 hours. If a GetLatestConfiguration call uses an expired token, the system returns BadRequestException.

Type: String

Pattern: \S{1,8192}

Errors

BadRequestException

The input fails to satisfy the constraints specified by the service.

HTTP Status Code: 400

HTTP Status Code: 500
